REVIEW
 Anastrozole selectively inhibits aromatase. The principal source of circulating estrogen (primarily estradiol) is conversion of adrenally-generated androstenedione to estrone by aromatase in peripheral tissues. Therefore, aromatase inhibition leads to a decrease in serum and tumor concentration of estrogen, leading to a decreased tumor mass or delayed progression of tumor growth in some women. Anastrozole has no detectable effect on synthesis of adrenal corticosteroids, aldosterone, and thyroid hormone.
